Myria is a private community and concierge for off-market goods & services — the things you can't Google. Ultra-high net worth individuals spend $390 billion per year ($1.3 million each) on lifestyle, but they still struggle to find everything they want. Why? Because the best of any category — homes, boats, restaurant reservations — the best stuff is never listed online. Likewise, the best people don’t need the internet to find a new client or job. The best is always off-market. Myria is the Off-Marketplace. Myria helps off-market sellers reach the nicest and wealthiest buyers. In turn, we help the world’s most successful people access the best of everything, give back, and get the most out of life. If it’s off-market, it’s on Myria!

Asseta is an online marketplace for used capital equipment and parts. We utilize innovative software to bring buyers and sellers together so you can efficiently and transparently collaborate during equipment transactions. Our web based platform ensures easy price discovery for interested parties and high touch customer service. Today over $100B is spent on used manufacturing equipment offline via brokers and middlemen. This huge but un-sexy market has yet to be transformed by technology. The incumbent firms rely on large sales forces and the fragmentation of the market to charge huge margins. We believe in a better solution. Founded in 2013, Asseta is Y Combinator backed startup based in Newport Beach. For more information, visit www.asseta.com.
